PORTABLE STACK-COVER.

Application tiled May 22,

To all whom it may concern:

Be it known that l, WILLIAM KJNDT, a citizen ol' the United States, residing at Belleville, in the county of Republic and State of Kansas, have invented certain new and useful improvements in Portable Stack-Covers, of which the following is a specification.

My invention relates to improvements in portable stack covers, my object being to provide protection tor hay, grain etc., against the deteriorating et'l'ects of the elements.

The cover is adjustable both in height and width to accommodate stacks oi different sizes, and may be quickly placed in position for immediate use, or taken apart for transportation from one part of the field to another. vWhen in position it effectually prevents the stack from being overturned by wind, excludes iain, snow and frost and thus renders skilful topping oi the stack unnecessary.

With these ends in view the invention may be said to consist in the novel construction, combination and arrangement of parts hereinafter described, illustrated in the accompanying drawing, and pointed out in the appended claims.

ln order that the invention may be fully understood reference will now be made to said drawing, in which Figure 1 represents a perspective view oi my Cover in position upon a stach, Fig. 2 is an enlarged vertical section of same with the lower portion of the center-pole broken away. Fig. 3 is a vertical section laken on line III-lll ol Fig. 2 with the conical top removed. Fig. 4 is a detail perspective view of an apron forming part of the invention. Fig. 5 is an enlarged inverted section taken on line V-V of Fig. 1 showing the detachable ends of a hoop forming part of the invention,

ln carrying out the invention I employ a center-pole l, around which the stack is formed, for supporting th e stack-cover and preventing the stack from being overtumed by wind. The lower end of said pole is preferably secured in the ground and its upper end 2 is tapered for the reception of a tapering ierrul'e 3 which snugly but detachably tits said upper end. Ferrule 3 is provided with a pair ol upwardly-extending arms 4 carrying a shaft 5 (heie shown as a bolt) upon which a pair ol sheave-wheels G are journaled, said sheave- 'lbe upper terminals of arms 4 are turned outwardly and downwardly lor the reception or' a conical cap 8 secured thereon and forming the apex ol the cover l'or the purpose of preventing rain, snow and frost from. entering the cover through a sleeve 9 loosely embracing ierrule 3 and provided near its upper end with a peripheral flange l0. Said sleeve is adjustably-supported by a pair or' hoisting-cables 11 extending in opposite directions over shcave-wheels 6 and attached at their upper terminals to the lower portion ol the sleeve. The upper portions of the hoisting-cables are oppositely-dis- Specification of Letters Patent.

l posed as shown in Fig. 2, so that when their lower porl tions are grasped for the purpose or' raising or lowering the sleeve the latter will not bind against the pole and thus add to the labor of adjusting said sleeve and the stack-cover carried thereby. By thus rendering the top ol the stack-cover adjustable it may be raised or lowered to accommodate stacks ol different heights, or ii a storm should arise while the stack is in course ol construction the cover may be lowered to the desired point for the protection of the grain or hay.

12 designates a conical top lor the cover consisting, preferably, of canvas in the shape ol a truncated cone, and detachably secured to the upper portion of the sleeve by a gathering rope 13 drawn around the canvas above l'lange l0 to prevent the upper portion of the top i'rom slipping downwardly upon the sleeve. The lower' portion of top 12 is expanded by a hoop 14 having overlapping ends one of which has a button 14a for engagement with a slot 14 'in the other end. Thus said ends may be readily disconnected so that the hoop can be eX- panded preparatory to removing it and top 12 from pole 1.

1n order that the hoop may be expanded as above described the overlapping sides of top 12 are laced together by hooks 15 and a rope 16 the lower end of which latter is wound about the button 14u and prevents the latter disengaging slot 14h. The upper end oi rope 1G is attached to rope 13 so that when the tormer is unlaced the latter may be unwrapped from the upper end ol" top l2 if it is desired to also remove said top from the sleeve.

18 designates a bail having a swiveled connection with the upper end ol the sleeve and adapted to be engaged by a hay-fork when it is desired to lift top l2 in position upon the stack or remove it therefrom. The body of this bail is oi a size to loosely embrace cap 8, so that when it is raised in an upright position its ends liit the cap and ferrule entirely otf the pole along with the cover, but when it is turned aside asshown in Fig. l its raising or lowering will adjust the cover without affecting the ierrule and cap.

The sides of the stack are protected by aprons 19 provided at their upper ends with hooks 20 ior detachably engaging the hoop, so that one or more of said aprons may be removed when it is desired to take material from the stack. Said aprons flare toward their lower ends so that their sides may be let out, and still overlap, to accommodate a large or conical stack. and their lower corners are provided with ropes 21 which are drawn in opposite directions around the stack and tied to prevent wind getting beneath the cover and blowing it from the stack. Il desired weights may be attached to said ropes to assist in holding the cover in position when exposed to a gale.

Rain is prevented from entering the cover at the top o the aprons by a Bange 22 integral with the lower portion of top l2 and overlapping the upper edges of said aprons.

23 designates a transverse pin adapted to engage anyone of a series of holes 24- in the pole, so that the cover may be positively supported at any desired height. It also assists in preventing the coverirom being blown from the pole and the stack when cables ll are attached to its projecting terminals 25m. 'vll In practice, the cover may be placed in position upon the pole and supported at the upper portion thereof by pin 23, preparatory to building the stack around the pole by hand, or ii a hay-fork is to be employed in building the stack thel cover is lett oft until the stack is finished, and then lifted in position by means of said fork, the bail 18 affording a convenient means for engagement with the fork.

After the material which formed the stack has been used, the cover may be removed in its entirety from the pole by means of the hay-fork, or, if preierred, it may be lowered to the ground and removed from the pole by hand aft-er the top has been unlaced and the ends oi the hoop unfastened. "nl

Having thus described my invention what I claim and desire to secure by Letters-Patent, is:-
